    摘要: Embodiments of this application provide an encoding method and apparatus, and a decoding method and apparatus, and relate to the communications field. In the method, a corresponding neural network unit may be generated based on a kernel matrix, and then an encoding neural network or a decoding neural network may consist of neural network units. In this way, the encoding neural network or the decoding neural network is obtained after small neural network units are connected, so that in an encoding/a decoding learning process, generalization can be implemented to entire codeword space by using a small learning sample, to weaken impact of information with a relatively long codeword on complexity and learning difficulty of a neural network.

    摘要: This application provides a data retransmission method and apparatus. The method includes: A transmitting device obtains information to be transmitted for a t th time, where the information to be transmitted for the t th time includes R t extension locations and information to be transmitted for a (t-1) th time, and the extension locations include M t information bits and L t check bits corresponding to the M t information bits. The transmitting device then performs Polar encoding on the information to be transmitted for the t th time, to obtain a codeword after the Polar encoding, obtains a codeword for (t-1) th retransmission based on the codeword after the Polar encoding, and transmits the codeword for (t-1) th retransmission. A receiving device performs polar decoding after receiving the codeword for (t-1) th retransmission, to obtain a decoding result of codewords for t times of transmission. By performing, on an encoding side, check encoding on the information bits in an extension part, a decoding path can be reduced in a decoding process, thereby greatly reducing decoding complexity, and reducing storage overheads and calculation overheads.
